@gemjuno I suggest you restart your kindle. I just upgraded from .28 to .30, rebooted, and I also couldn't connect over SSH via wifi even though I could ping it. I restarted the kindle again and it's fine now.

Not sure if this is related, but normally when you leave the usb cable in the kindle and restart, it'll be mounted after it starts up. But you if leave the cable in and restart from an update, it doesn't automatically mount. So something post-update makes the kindle behave differently.

guys i appreciate all your advices and took into account all of them. i rebooted both kindle and router but still no luck. putty and filezilla connections over usb still work fine as well as i can ping too.

@NiLuJe:I copied new config from src to kindle and edited before I restart.

@gemjuno It may not make a difference, but I've never tried configuring usbnet to work over usb so that is one clear difference of my config to yours.

You certain you don't have any firewall software on your local PC that may be blocking your access to port 22? Sure it works over USB networking, but since that is a different interface, it may not be under the same restrictions. Also, some wireless access points have an isolation setting that prevents wireless clients from interacting with other wireless devices.

@badbob001 I do have firewall on my pc but I'm sure it accepts connection on port 22 as I tested MobaSSH with putty from other computers. Also my router supports isolation but I disabled long before I setup my kindle. My problem has been totally a mystery so far.

I'm having problems with getting ssh working wirelessly, as well. I have usbnetworking working, and I can ssh in from my Macbook using a cable, but I can't ping my Kindle using the wifi address. I've confirmed the Kindle's address (both with the 711 command and checking the MAC address in the router's device list), but all attempts to ping time out. I set the entry in the config file (K3_WIFI="true"), but I'm not sure how to confirm that it worked correctly (obviously, I'm guessing it didn't) There are no errors in the logs that look like NiLuJe's message to gemjuno in post #40.

Can someone give me a push in the right direction, please? What am I missing?

Yeah, see, that's where I'm confused. I can ping every other device in the list - other computers, Tivos, WD live TV - so I know that's not the problem. I know the Kindle is connected to wifi - I can use the browser to surf/download books - so I know that's not the problem. And that's where I sit. What on earth could be causing it?

ETA - FBKindle - that's what - when I stopped it (not just switched back to the Kindle framework) the ping started working.

That's where framing the question on a board like this really helps - thanks. On to the next steps.

the only special thing that happens when fbKindle stops is that the [Qt keyboard]
driver stops grabbing /dev/input/event0 , /dev/input/event1 (and /dev/input/event3 -- on K3).
